This study compares a new regenerative approach using injectable platelet-rich fibrin (i-PRF) to standard retreatment for teeth with persistent infection after a root canal. 140 adults with single-rooted front teeth will be randomly assigned to one of the two treatments and follo…

This study looks at whether people with Takayasu arteritis, a rare blood vessel disease, can stop taking biologic drugs after being in remission for a long time. About 40 participants who have been on biologics for at least 3 years will slowly reduce their dose over 3 months, the…

This study aims to find out how well common physical tests (like Cozen's test) and ultrasound can diagnose tennis elbow (lateral elbow tendinopathy). Researchers will enroll 100 adults aged 18-60 with one-sided elbow pain. The goal is to measure the sensitivity and specificity of…

This study explores whether people with Parkinson's disease can improve their quality of life, walking speed, and mobility by managing their own exercise plans at home using telerehabilitation. Researchers will compare the results to those from a supervised exercise program. The …

This study looks at whether avoiding opioids during lumbar spine surgery can still control pain while reducing side effects like nausea and constipation. About 75 adults having elective back surgery will be split into three groups based on the anesthesia they receive: opioid-free…

This study looks at whether a steroid injection in the spine can improve how well people with chronic neck pain sense their arm's position. Researchers will measure arm movement accuracy before and after the injection in 46 adults. The goal is to see if the injection helps with m…

This study looks at whether a physiotherapist-led online exercise program can reduce pain and improve physical function in remote white-collar workers. About 33 adults who work from home and have low back or neck pain will take part. They will follow a guided exercise routine, an…

This study looks at whether adding special balance exercises to regular aerobic and strength training can improve balance, walking, and overall fitness in people who are overweight or obese. Forty adults with a BMI between 25 and 35 will be split into two groups: one doing standa…

This study tests whether doing guided exercise sessions from home (telerehabilitation) can improve exercise ability, breathing, fatigue, and quality of life in adults with elevated pulmonary artery pressure. About 12 participants will be randomly assigned to either an 8-week tele…

This study looks at how metabolic markers (like insulin resistance and body measurements) relate to pain and a condition called central sensitization in women with lipedema. Researchers will measure pain levels and sensitivity in 59 women. No treatment is given—this is an observa…

This study uses ultrasound to check for signs of inflammation in the tendons of people with tennis elbow (lateral epicondylitis). Researchers will compare the ultrasound scores of 60 participants with tennis elbow to healthy volunteers. The goal is to better understand if people …

This study looks at how nutrition (measured by a score called CONUT) is linked to balance and daily function in people who had a stroke at least 6 months ago. Researchers will also check muscle thickness, arm size, and bone density. The goal is to understand these connections, no…

This study aims to see if a new scoring tool called SOFA-2 can better predict which ICU patients are at risk of dying within 30 days compared to the current standard. Researchers will also measure how common sepsis is in Turkish intensive care units. About 2,500 adult ICU patient…

This study looks at whether the natural pulsation of the spinal cord lining (dura) is linked to pain and disability in people with lumbar spinal stenosis, a condition where the spinal canal narrows. Researchers will measure dural pulsation on MRI and compare it to patients' repor…

This study looks at how muscle stiffness (spasticity) appears in the arms and legs of people with multiple sclerosis and how it affects their daily life. Researchers will examine 75 adults with MS to classify different spasticity patterns and link them to quality of life. The goa…

This study is a global registry that will collect information from 1,000 people with Takayasu arteritis, a rare disease that causes inflammation of the large arteries. Researchers will look at patients' medical history, test results, and treatments to better understand the diseas…

This study looks at whether two easy-to-calculate scores (Shock Index and Modified Shock Index) can predict which women will have dangerously low blood pressure after receiving spinal anesthesia for a planned C-section. Researchers will monitor 300 pregnant women and track how of…

This study aims to measure how accurately people with cervical radiculopathy (nerve pain from a slipped disc in the neck) can sense the position of their arm, compared to healthy volunteers. Researchers will use a simple reaching test to assess arm position sense and link it to p…

This study looks at how well parents recognize and respond to their baby's needs, and whether that affects common problems like sleep trouble, feeding issues, and excessive crying. About 249 parents and their infants (6-36 months old) will fill out questionnaires. The goal is to …

This study monitors the nutritional health of 57 head and neck cancer patients during radiotherapy. Researchers regularly check body composition, muscle strength, food intake, and quality of life to spot early signs of malnutrition. The goal is to understand nutrition-related cha…

This study is adapting a sleep screening questionnaire for Turkish children and teens with complex chronic conditions (like multiple long-term health issues). Researchers will check if the tool is reliable and accurate, and also look at how common sleep problems are in this group…

This study looks at how seeing, smelling, and interacting with food in virtual reality changes food cravings and body responses. Thirty-four healthy adults will have their brain activity, saliva, blood sugar, and temperature measured while exposed to real and virtual food cues. T…

This study looks at whether women with lipedema have more foot arch problems and joint looseness than women without the condition. Researchers will use foot X-rays and flexibility tests to compare the two groups. The goal is to better understand how lipedema affects foot function…

This study is testing whether giving magnesium sulfate during chest surgery that uses only one lung can improve oxygen levels and lung function. Researchers will compare patients who receive magnesium as part of their standard care to those who do not. The goal is to see if magne…
